Scientists are seriously searching for the existence of extraterrestrial life forms.
Various extraterrestrial life forms appear in that sci-fi movie.
Related words 宇う 宙ちゅう 人じん 宇宙人 is a more common, casual term for 'alien' or 'space person', often implying intelligent beings, while 地球外生命体 is a formal, scientific term that can include any life form, not necessarily intelligent.
異い 星せい 人じん 異星人 also means 'alien' or 'being from another planet', similar to 宇宙人 but slightly more literary. 地球外生命体 is broader and more technical.
Etymology Compound of 地球外 (extraterrestrial) + 生命体 (life form). The exact historical derivation is uncertain, but the term follows standard scientific word formation patterns in Japanese.
